Social media is awash with reports of Amazon's popular personal assistant chortling and chuckling at unexpected times, sometimes during an unrelated command and occasionally in the middle of the night, seemingly unprovoked.

"So Alexa decided to laugh randomly while I was in the kitchen. Freaked @SnootyJuicer and I out. I thought a kid was laughing behind me," Twitter user @CaptHandlebar wrote Feb. 22 with a video of Alexa chuckling unprompted.

Even those who haven't experienced the unprompted laughter have been trying to get in on the fun -- if you can call it that -- posting videos asking Alexa to laugh on command for them. The personal assistant's laughs range from a dainty 'tee-hee' to a throaty, maniacal cackle, the same laugh that many users report hearing out of the blue.

In a statement to ABC, Amazon acknowledged that Alexa can mistakenly hear the phrase "Alexa, laugh," which it will soon disable. The company is working on a fix to change the laugh command to "Alexa, can you laugh?," which a company spokeswoman said is less likely to produce a false-positive response.

Alexa will also say "Sure, I can laugh" before actually laughing to make it clear that she is responding to a command.

Amazon's line of Alexa-enabled speakers are one of the most popular available, with one study claiming that the line dominates more than 70 percent of the quickly growing market.
